    • A process for purifying an impure vinylically-unsaturated organosilicon product compound prepared by reaction between a vinylically-unsaturated organosilicon precursor and a halogenated organic compound in the presence of a homogeneous zerovalent palladium catalyst complex, the catalyst complex including an organophosphine or organoarsine ligand, in the presence of a hydrogen halide acceptor in an essentially anhydrous diluent, comprising treating a mixture containing the impure vinylically-unsaturated organosilicon product compound with a peroxide for a time sufficient to oxidize organophosphine or organoarsine impurities present in a mixture being treated. The peroxide can be selected from aqueous hydrogen peroxide or organic peroxides. The thus-treated mixture can be further treated by chromatography over silica gel or alumina. In optional embodiments, chromatography over silica gel or alumina can precede treatment with the peroxide.
    • 一种在均相的零价钯催化剂络合物(包括有机膦或有机砷配体)的催化剂络合物的存在下,通过在乙烯基不饱和有机硅前体和卤代有机化合物之间的反应制备的不纯的乙烯基不饱和有机硅产物化合物的方法, 在基本上无水的稀释剂中存在卤化氢受体,包括用过氧化物处理含有不纯的乙烯基不饱和有机硅产物化合物的混合物足以氧化存在于待处理的混合物中的有机膦或有机砷杂质。 过氧化物可以选自过氧化氢水溶液或有机过氧化物。 这样处理的混合物可以通过硅胶或氧化铝上的色谱进一步处理。 在任选的实施方案中,硅胶或氧化铝上的色谱可以在用过氧化物处理之前进行。
